ABSTRACT
This study was undertaken to study the influence of construction deficiencies on hysteretic behavior of exterior
beam-column connections. Building stock survey was conducted in five major cities of Pakistan for identification and
quantification of material and detailing disparities between design specifications and construction practices. The effect
of these disparities was studied using quasi-static cyclic testing on two exterior beam-column connections; EJ-1A
(code-compliant) with no deficiencies and EJ-2A (non-compliant) incorporating all identified deficiencies. Damage
patterns and hysteretic force-deformation behavior of these models is presented and the performance of the two
specimens is compared. The study found that moderate to high deficiencies exist between design specifications and
construction practices for the construction of RC buildings in Pakistan. The study also concluded that significant
loss of strength and ductility is observed between code-compliant and non-code-compliant exterior beam-column
connections subjected to reverse cyclic loading.
